SEALING-CAP FOR BOTTLES.

I cation.

The present extensively employed cap for bottles consists of a cork diskwithin a soft metal cap, which has an annular corrugated flange adaptedto embrace a shoulder on the neck of a bottle. In applying this cap to abottle, it is customary to press a conical hood against the .cap toforce the inner corrugations into firm locking engagement with theshoulder on the neck of the bottle, and also to firmly embed the lip ofthe neck in the cork disk within said cap. Many devices are employed toremove the cap, the most common being a lever adapted to engage thelower edge of the annular flange. and fulcrumed on the top of the cap.These bottle opening devices, though simple, entail considerable expenseon account of the large number required, and much inconvenience oftenresults when they are lost or misplaced.

The object of my invention is to provide on a bottle cap of. this kind,a sheet metal thumb piece, integral with the cap, adapted to normallylie close to the periphery of the cap so as to avoid interference withthe operation of ordinary sealing devices, said thumb piece being alsoadapted to be bent slightly outward from the cap when it is applied to abottle, after which it may be easily grasped and bent to form a leversufficiently rigid to remove the cap from the bottle.

In the drawings, Figure 1 is a perspective view of my improved sealingcap, the parts thereof being in normal osition, before application tothe bottle; Fig. 2 1s a central sectional viewthereof; Fig. 3 is asimilar view, showing the cap as applied to the mouth of a bottle; andFig. 4 is a side elevation of a cap and illustrates in perspective thethumb iece bent to form a detaching lever for said cap.

Referring to the drawings, 1 have used the reference numeral 10 toindicate the top of my improved cap, and 11 the annular sealing flangethereon. This flange is corrugated para el to the axis of the cap, thenner folds of the corrugations being desig- Specification of LettersPatent.

nated by the numeral 12, and the outer folds by the numeral "13. Myopener A, formed integral with the flange 11, is normally folded againstthe periphery of said ca (Figs. 1 and 2). Said opener consists o a body14 having wings 15 at the sides thereof. These wings are offset at 16where they join the body 14 to provide definite lines-of-fold upon whichsaid wings may be turned and the tips 17 of the wings are curved inwardand rest between outer folds 13 of the cap.

At the top of the body.14 is. formed a small 1 projection 14 which innormal position fits snugly against the top of the cap. It will be seenthat the thumb piece in this position conforms closely with the contourof the cap and is, therefore, adapted to use in the standard bottlesealing devices, which employ conical hoods to press the sealing capsupon bottle shoulders. When my improved cap is applied to the mouth of abottle, the thumb piece A is bent slightly out-- ward by the conicalhood- (Fig. 3) and the projection 14 on the body 14 can then be easilygrasped preparatory to bending the thumb piece into the form of adetaching lever. To remove the cap, said projection .is caught by theuser and the thumb piece bent outward until. the body 14: issubstantially at right-angles to the flange 11. The wings 15 are thenbent back on the lines-offold 16, the inner edges thereof restingagainst the peripher of the cap, thus reinforcing the body 14- Fig. 4:)Upward pressure exerted, against the now rigid body 14: causes thelateral distortion of the annular sealing flange 11 and a wrenchingforce against the cap which results in releasing the inner corrugations12 from looking engagement with the shoulder 19 of the bottle and inremoving the cap from the bottle.

My opener may be made a part of the cap at slight expense and does notform an objectionable projection either before, during,

bottle.

Having described my invention, what 1 i claim as new and desire toprotect by Letters Patent, is:

1. A. metallic sealing cap having a flange adapted to be bent intolocking contact with a bottle head, and an opener integral with the capand normally resting in close contact with the periphery thereof,'saidopener consisting of a body adapted to be bent outward from the flange,and reinforcing wings on the body designed to be bent substantially atright-angles thereto and to bear against .the cap.

' 2. A metallic sealing cap having a flange adapted to be bent intolocking contact with a bottle head, and an opener integral with theflange and normally folded in close contact against the peripherythereof, said opener being adapted to be initially bent outward by theordinary bottle sealing device and also adapted to be further bent bythe fingers to form a rigid detaching lever.

3. A cap for bottles comprising a metal top having an annular corrugatedsealing flange, and an opener, integral therewith, consisting of a sheetmetal body having an inturned projection thereon and wings with inturnedtips, said opener being adapted when in normal position to lie closeagainst the periphery of the flange, said projection resting against thetop of the cap and the tips lying between outer folds in thecorrugatedflange, the body of said opener being adapted to be bentsubstantially at rightangles to said annular flange while the wings areturned with their rear edges against said flange to form a reinforcementfor said body.

4. A metallic sealing cap having a flange adapted to be bent intolocking contact with a bottle head and an opener integral there-' withconsisting of a sheet metal body hav- 1ng wings and a curved projectionthereon,

said opener being adapted when in normal position to lie. close againstthe periphery of the flange with said projection resting against the topof the cap, said body being adapted to be bent slightly outward by theordinary bottle sealing device and. also adapted to be further bent bythe fingers to a position substantially at right-angles to said annularflange, while the wings are turned up with their rear edges against said1Llzlalige to form a reinforcement for said 5. A metallic sealing canhaving a flange adapted to be bent into locking contact with a bottlehead and an opener integral therewith consisting of a sheet metal bodyhaving wings with curved tips thereon, said opener being adapted when innormal position toi lie close against the periphery of the flange withsaid curved tips resting between the outer folds of said flange, saidbody being adapted to be bent slightly outward by the ordinary bottlesealing device and also adapted to be further bentby the fingers to aposition substantially at right-angles to said annular flange, while thewings are turned up with their rear edges against said flange to form areinforcement for said body.

Whereof, l have hereunto subscribed my name to this specification.
